  • platelet-shaped synthetic substrates are coated below an average thickness of 50 nm with, for example, high-index metal oxides, extremely fragile pigments are obtained which can break even when incorporated into an application medium, which in turn results in a significant reduction
  • Pigments have a particularly high photocatalytic activity. Accordingly, undesirable discoloration of a TiO 2 -containing pigment occurs very easily
  • water-based oligomeric silane systems can also be non-water or sparingly soluble groups, such as alkyl groups of silanes, easily bind to the surface of the pearlescent pigments.
  • the resulting water-based oligomeric silanes ie water-based organopolysiloxane-containing compositions, are substantially free of organic solvents and have a flash point of greater than 70 ° C.

A larger AE * value of the loaded sample relative to the unloaded restoring pattern thus means a lower UV stability of the examined pigment.
